Lastest Build Release Notes

Build 919 : Mac Simulator/iOS: All iOS builds are now built against the iOS 6 SDK now that it is official. The daily build drop down box for SDK will no longer appear. All users should be building with this moving forward. Backwards compatibility is unchanged for the moment and should still theoretically support 4.3 and up, though actual testing is very minimal.

Corona Announcements

In episode 5 we talked about using the new Default-568h@2x.png for your iPhone 5 project. Just to clarify, adding Default-568h@2x.png to your iOS app project is an Apple requirement, not a Corona SDK requirement. While we’re still not solid on the reasoning for the name of this file, Dean Murphy, developer of Joke Shake, was nice enough to offer up the speculation that Default-568h@2x.png is half of 1136 (the iPhone 5 screen height). This is the best suggested answer we’ve heard so far, so we’ll go with that for now. Here’s his config.lua that sets screen size to the correct resolution for either iPhone’s, iPhone 5 or iPad’s

Newbie Questions

What’s the difference between local, global, and super global variables in Lua? Dr. Brian Burton explains all three and makes recommendations about why you’d want to use one over another.

After the show Dean Murphy commented that he didn’t use all of the things we mentioned in the show to create his Joke Shake app, but here are the Corona SDK doc references just in case you’d like to implement some of them in your app.

Brian Burtonsays:

Just wanted to give a reference for the _G global variable discussion. If you look it up in the lua language guide, it states that the _G is a variable that holds the global environment. Thus referencing a global variable through _G (i.e. _G.var) is a direct way to access any global variable. http://www.lua.org/manual/5.2/manual.html#6.1
